Wmmmm To allwhom it may. concern:

- Be it known that l, KARL l), SMITH, a

citizen of the United States, rcsldingat .Battle Creek, county ofCalhoun, State oi Miohigan, have invented certain new and usefulImprovements in lflmulsiiiyimg-lllachines, of which the following isaspecification.

This invention relates to improvements in emulsifying machines.

My improvements as herein illustrated are particularly designed by mefor treating; milk or cream or mixing butter or fat with milk or cream,although desirable for use in emulsifying or mixing other substances.

The main object of my invention is to provide an improved device of theclass dc-- scribed in which accurate and fine adjustments are possibleand easily accomplished.

Further objects, and objects relating to structural details, Willdefinitely appear.

from the detaileddescription to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure Which is a preferredfemhodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure l is an elevation of a structure em bodying the features of myinvention.

Fig. 11 is a detail view mainly in central vertical section.

' Fig. ill is a bottom View Fig. IV is a cross section on a linecorresponding to line H of Fig, ll.

In the drawing, similar reilerence characters refer to similar partsthroughout/the several. views.

Referring to the drawing, it provide a body or casing 1 having a chamber2 there in and a bore 3. At the luv/er end of the here 3 is an inlet lto which the lateral inlet or supply pipe 5 connected.

The chamber 2 is provided With a lateral discharge 6. The conical valvemember seat Tiaces into the chamber, the bore 3 being central of thisvalve member seat. The valve member Sis conical to correspond to thisseat, and is provided With a stem 9 ex- Specification ct L'IettersPatent.

low the inlet 4., the packing gland A packing ii is providedfor the stemhe l2 being secured to the end of the casing by the tap screws 1.3. Theportion. ll oi the stem lit-- ting the bore 3 is cut away at 15 toprovide passages fromthe inlet 4-. to the valve seat, there being adistributing groove 16 just below the valve meinhen 8, so that theliquid is uniformly distributed to the valve member seat from thesepassages, there beri tour of them in the structure illustrated. lhevalve iemher 8 is retained upon the stem hy the clamping nut il.

The n'iovement oi the valve member from ts seat is determined and thevalve is fixedly supported when. under pressure by an art usting meanscomprising in. the structure illustrated the members l8, l9, and 20. Themember 18 is a bushing-like casing member threed ed into the casing andinternally threaded to receive the outer member 19., Which is internallythreaded to receive the member 20. The member 19 is provided with anadjusting hand Wheel 21.

The inner member E20 engages the valve constituting in effect athrustmember therefor. The member 20 is held against rotation by the lugs orlateral portions 22 there on. Which coact with lugs on the member 18.The threads of the members 19 and 90 are oi'dili'ercnt pitch, no eil'ortbeing made to accurately illustrate the. diilerence in pitch, as it Willbe understood that the purpose is to secure a very time and accuratendjustmeut for the valve, and also a. powerful means of adjustment 'vlhich cnahlcs this the and accurate adjustment of the valve While underhigh pressure.

The extension oi? the stem 9 through the casing, however, and thedelivery oi the fluid under pressure through the inlet 4, against.

3 the side instead oi against the end oi? the valve stem, very'inaterially reduces the end tion of end thrust is apparent.

l have illustrated and described my improvements as I have en'ihodiedthe same in one form. I have not attempted. to illustrate or descriheother adaptations or mcdifica tions, as l believe the disclosure madewill ll atented deptrlcl, llllll, Application filed may in, will.fierial lilo, ceaeea llil enable those skilled in the art to which myinvention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Let I ters Patent is:

1. In a structure of the class described, the combination with a casinghaving a valve member chamber, an upwardly facin valve member seat, abore centrally of sai seat, a lateral connection at the lower end ofsaid bore, and a lateral discharge connection above said-valve seat, avalve member coacting with said seat provided with a stem disposedthrough and guided by said bore and projecting1 through the end of theeasing, said stem aving cutaway portions within said bore providingpassages from the inlet to the valve seat, a packing for the projectingend of said'stem disposed below said inlet, a means for fixedlysupporting said valve member comprising a air of adjustin members,the-ihnefof which engages the v, ve member and has threaded engagementwith the outer, and is provided with laterally projecting lugs, and abushing-like casing member into which theouter adjusting member isthreaded provided with parts 00- acting with said lugs to support theinner adjustin member against rotation, said outer adjusting memberbeing provided with an adjusting handle.

2. In a structure of the class described, the combination with a casinghaving a valve member chamber, an upwardly facing valve member seat, abore centrally ofsaid seat, a lateral connection at the lower end ofsaid bore, and a lateral discharge connection above said valve seat, avalve member coacting with said seat provided with a stemdisposed throuh and guided by said bore and projecting t rough the end of the casing,said stem having cutaway portions within said bore providing passagesfrom the inlet tothe valve seat; a packing for the projecting end ofsaid stem disposed below said inlet, a means for fixedly supportin saidvalve member comprising a pair 0' adjusting members, the inner of whichengages the valve member and has threaded engagement with the outer theouter having threaded connections with the casing.

' 8; In a structure of the class described,

the combination with a casin having a valve member chamber, an inwar lyfacing valve member seat, a bore centrally of said seat,

a lateral connection at the lower end of said bore, and a lateraldischarge connection above said valve seat, a valve member coacting withsaid seat provided with a stem disposed through and guided by said bore,and projecting through the end of the casing, said stem having cutawayportions within eral inlet and outlet and a valve seat 1neniber seatbetween said inlet and outlet, and a bore centrally of said valvemember. seat, and into which the inlet opens, a valve member coactingwith said seat provided with a stem disposed through said bore andprojecting through the end of the casing, a packing for the projectingend of'said stem, a means for fixedly supporting said valve membercomprising a pair of adjusting means, the inner of which engages thevalve member and has threaded engagement with the outer, and is providedwith laterally projecting lugs and a bushing-like casing member intowhich the outer adjusting member is threaded provided with partsooacting with said lugs to support the inner adjusting memberagainstrotation, said outer adjusting member being provided with an adjectingthrough the end of the casing, a

packing for the projecting end of said stem, a means for fixedlysupporting said valve member comprising a pair of adjusting means, theinner of which engages the Valve member and has threaded engagement withthe outer, the outer having threaded connections with the casing.

6. In a structure of the class described, the combination with a casinghaving a lateral inlet and outlet and a valve seat member seat betweensaid inlet and outlet, and a bore centrally of said" valve member seat,and into which the inlet opens, a valve member coacting with said seatprovided with a stem disposed through said bore and projectin throughthe end of the casing, a packing for the projecting end of said stem,and a means "for fixedly supporting said valve member.
